Abstract
The invention provides a processing method of a carbonized pencil lead. The processing method is characterized by comprising the following steps: (1) soaking willow strip offal in water at a temperature of 10-20 DEG C, extracting out impurities, and smashing the willow strip offal into powder; (2) adding 15-20kg of kaolin, 6-8kg of powder mixture, 25-30kg of polymerized wax and 10-16kg of pigment into 100kg of the main ingredient; (3) uniformly stirring raw materials of the step (2), and kneading the mixture in a kneader at a temperature of 30 DEG C; (4) rolling the kneaded material; storing the rolled material which has the thickness of 0.3-0.5mm and water content of 15% for 48 hours; (6) putting the material obtained in the step (5) into a lead presser, and extruding to obtain a pencil lead with the diameter of phi 0.4 or phi 0.5.
Description
Technical field
The present invention relates to pencil manufacture field, relate in particular to a kind of carbonization lead for retractable pencil processing method.
Background technology
Charcoal bar is a kind of traditional drawing articles for use, be used for that traditional Chinese Painting is made a draft or sketch, generally by willow bar or other tree branches process imperfect combustion, or pyrolysis under the condition of isolated air, the dark brown or the black porosu solid carbide that form, people directly bring sketch formation traditional Chinese Painting and make a draft, this charing bar is softer, powdered carbon easily drops, frangibility and the hand of easily making dirty, for beginner, using is a very large trouble, adds waste timber resources, therefore never bring into play maximum value.
Summary of the invention
The present invention is mainly for present situation, and the problem occurring above.A kind of carbonization lead for retractable pencil processing method is provided.Its objective is and utilize existing process technology, take charcoal bar as raw material, through batching processing, produce charing lead for retractable pencil, realize the transformation of high attached value, provide direction for producing high-grade pencil, realize the effect of high added value.
The present invention is achieved by the following technical solutions, developed a kind of carbonization lead for retractable pencil processing method, it is characterized in that comprising the following steps:
(1) offal of willow bar is immersed in the water of 10-20 degree Celsius, extracts magazine, be ground into Powdered.
(2) major ingredient 100kg places kaolin 15-20kg, powder mixture 6-8kg, polymer wax 25-30kg, pigment 10-16kg.
(3) batching of step (2) is stirred, make all materials all completely evenly, put in kneader and mediate 3 hours, temperature keeps 30 degrees Celsius.
(4) put the material after mediating into roller and roll, will roll material thickness is 0.3-0.5 millimeter, then tests water content to 15%.
(5) moisture 15% material is placed in holding vessel, in tank, puts cotton-wadded quilt and place 48 hours, make material full and uniform.
(6) material of step (5) is put into and pressed core machine, the lead for retractable pencil of extruding Φ 4.0 or Φ 5.0 comes.
(7) lead for retractable pencil is directly dried with hand rubbing.
The good effect of invention is: the present invention is take willow bar or its offal as basis, by the production technology of science, develops and replaces drawing charcoal pencil, has reduced resource and the offal of willow bar is fully utilized, and obtains maximum return.Because technique of the present invention is to improve on existing technique basis, plant machinery etc. is not improved, so can directly apply in production technology, simple.
Specific embodiment:
Embodiment 1:
First prepare material: the willow bar offal of getting 100kg.Batching: kaolin 20kg, adhesive 6kg, polymer wax 26kg.Batching is stirred, under 30 degrees Celsius of normal temperature, mediate 3 hours, rolling material thickness is 0.3-0.5 millimeter, moisture content is containing 15%, get 48 hours above materials and extrude hard charing lead for retractable pencil by 4.0 core pipes, hard charing lead for retractable pencil is produced to carbonization pencil by producing the production technology of common lead for retractable pencil.
Embodiment 2:
First prepare material: the willow bar offal of getting 100kg.Batching: kaolin 15kg, adhesive 7kg, polymer wax 28kg, pigment 16kg.Ready batching is stirred.Under 30 degrees Celsius of normal temperature, mediate 3 hours, rolling material thickness is 0.3-0.5 millimeter, moisture content, containing 15%, is got 48 hours above materials and is extruded soft charing lead for retractable pencil by 4.0 core pipes, and soft charing lead for retractable pencil is produced to carbonization pencil by producing the production technology of common lead for retractable pencil.
In actual applications, those skilled in the art completely in technical scheme of the present invention, other parameters of choose reasonable, but the technical scheme substance of protecting with the present invention is identical, still falls within the scope of protection of the present invention.
